To a?! who/ndt may con-cern:

Be it known that I, WILLIAM J. PLATTEN, a citizen of the United States, and resident of Green Bay, in thel county of Brown and State of lVisconsin, have invented certain new and useful Improvements in Refrigerating Counters; and I do hereby declare that the following is a full, clear,v and exact description thereof.

This invention counters. v j

Y Objects of this invention are to provide a refrigeratin'g counter in which the refrigeration is secured directly by conduction from a refrigerating elementin the counter top, in which there is no iow of refrigerant air around the articles to be cooled, in which the counter top itself, or a portion associated therewith, is maintained at a relatively low temperature, and in which there is no con` densatioi from a traveling stream of refrigerant air. j

Further objects are to provide a refrigerating counter in which the material or food.

may be openly and directly displayed on top of counter, kept cool, and free from flies,-

and be readily accessible for rapid selling,

in which a minimum of insulation is required, and which may be easily kept ina clean and sanitary condition, and the refrigerating element of which may be easily -installed in old counters.

Embodiments of the invention are shown in the accompanying drawing, in which Figure 1 is a sectional view through. one form of refrigerating counter, such view corresponding to a section on the line 1-1 of Figure 2.

Figure 2 is a plan view of the structure shown in Figure 1 with parts broken away. Figures 3 and 4 are views corresponding to Figure 1 showing different modifications. Figures 1 and 2 showing one form of the invention will first be described. The counter 1 in this form of the invention may consist of a slab of marble which is continuous from one side to the other..

tion of heat to the pipes. This metal is preferably of rectangular cross section, and of elongated contour as illustrated y It is-held in a cork, lith or other' thermal insulating case or packing 4 and `if desired felt washers 5 may be positioned between such packing and the marble slab 1 on opposite sides of the metal block. Any-desired support maybe provided for the counter andv preferably a transparent shield 6 extends partially thereover.

In using' this counter, the containers 7 for the food or other material are 'placed directly upon the marble slab andl over the metal block 3 as shown in Figure 1. The heat is readily conducted from these containers and from the food therein, downwardly through the slab and into the metal block and from thence thro-ugh the pipes to the refrigerant.

It is to be noted' that very little loss occurs in this type of construction as the insulatlon 4 adequately protects the. metal block and cooling pipes therein.

Figure 3 shows a device in which the counter 8 is cut away to provide an aperture adapted to receive containers 9. These containers may directly to provide a rectangular channel adapted to receive a rectangular casing 13 through which the cooling medium may pass. The upper' portion of this casing 11, which is preferably of metal, is vlushwith the upper portion of the counter 12. The lower portio-n of the casing and also the adjacent portions of the counter are insulated by the elongated insulating member 14 in a manner similar to that previously described.

It will be seen that refrigerating counters have been provided which arelof extremely effective design, which do not depend upon continuously circulating coldair with consequent'condensation, which may be most readily installed, and which may be easily kept in a sanitary and clean condition.

.Although a few forms of the invention have been described in considerable detail,

-it is to be understood that the invention may take various forms and is, therefore, to be further form ofthe limited only as set forth in the appended l upon the under side of said slab.
